时间转换报java.lang.NumberFormatException: multiple points问题
java.lang.NumberFormatException: multiple points at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:1101) at java.lang.Double.parseDouble(Double.java:540) at java.text.DigitList.getDouble(DigitList.java:168) at java.text.DecimalFormat.parse(DecimalFormat.java:1321) at java.text.SimpleDateFormat.subParse(SimpleDateFormat.java:1793) at java.text.SimpleDateFormat.parse(SimpleDateFormat.java:1455) at java.text.DateFormat.parse(DateFormat.java:355)
偶偶会报java.lang.NumberFormatException: multiple points或者报java.lang.NumberFormatException: For input string: ".31023102EE22"
原来是SimpleDateFormat是非线程安全的，在多线程情况下会有问题，在每个线程下得各自new SimpleDateFormat()就可以了
